Development of a Web-based Donor Eligibility Expert System

Background: The determination of blood donor eligibility has become critical and challenging to blood operators as so many conditions and restrictions should be considered to correctly decide the donor eligibility. Since the launching of the BIMS (Blood Information Management System) in May 2003, the demand of developing a more intelligent system to assist the determination of donor eligibility has been growing. The Korean Red Cross Blood Service intended to develop an expert system for donor eligibility determination with high efficiency and ease of use. Methods: The content of the system was determined through the activity of a team consisting of medical doctors, nurses, safety managers, and the system developers. Algorithms were developed according to the donor history taking process. The efficiency of the system was tested by the comparison of the time needed for inquiries and the number of inappropriate blood collections before and after the implementation of the new system. Results: The new system's user interface integrated many complicated work processes with a user-friendly flexibility. The types of decision included the restricted donations. The donor interviewers were highly satisfied with the system because almost all cases were correctly determined in a relatively short time. Using this system, the number of inappropriate blood collections was significantly lowered. Conclusion: We developed an expert system that can aide the donor eligibility determination process and prevent the violation of the related regulations. This system will contribute to enhancement of the blood safety as well as donor protection for our blood services.
